Equilibrium Expressions

Q. Write the equilibrium-constant expression for the reaction shown in terms of [NO], [O2], and [NO2]. 2NO(g) + O2(g) ⇌ 2NO2(g) Kc, which is sometimes symbolized as K or Keq, denotes that the equilibrium constant is expressed using molar concentrations. For this equation, Kc means the same thing as K and Keq.
